Interpreting Discharge Test Results
1. If discharge time is 60 minutes or higher, the problem is not with the batteries.
2. If discharge times are low, compare individual battery voltages recorded in step No. 6 above. If any bat-
tery shows a 0.4 volt or greater variance, the battery is bad or nearing the end of its useful life and
should be discarded or grouped with other batteries at or around same voltage. The voltage of a bad
battery will drop more rapidly near the end of the discharge than that of a good battery.

3. If all the batteries are within 0.30 volts of each other, but the discharge time is low, the batteries are
approaching the end of their life and the whole set will have to be replaced. In general, cars that dis-
charge in less than 60 minutes at 78°F on the discharge test will not normally make 36 holes. However,
discharge time is dependent on the electrolyte temperature. The table shown gives the discharge times
at various temperatures of a set of batteries that delivers 62 minutes at 80°F.
